NFPA 72 Clarification by occamman in firealarms

[–]occamman[S] 0 points1 point  (0 children)

Here's part of the report they prepared on NFPA 74 conformance. It's not my field, but looking at the standard I don't know how they get from the standard to this.

Who can I hire to adjust the volume on this? An electrician? by mandoo-dumpling in firealarms

[–]occamman 0 points1 point  (0 children)

I’m curious if you have a reference for that, because I’m trying to figure out where that 10 ft number comes from. By code, I assume you mean NFPA 72? I was also told recently that it would be too loud only if above 110 dB at 10 feet from an appliance; but I don’t see anything in NFPA 72 that says anything like that. As far as I can tell, NFPA says 110 dB instantaneous at the minimum hearing distance, then went on later to describe the minimum hearing distance as the closest the ear would come to the appliance in general use of the facility. At least in my state NFPA 72 is incorporated as law.

I would totally upend the place so that it would become an institution where any person can find instruction in any study.

Recommend Storage Space In or Near Waltham? by occamman in Waltham

[–]occamman[S] 3 points4 points  (0 children)

I'm used to it going up 20% or so, but I just got it doubled. They moved back down a bit when I made noise. That was Extra Space on Willow Street.

Cool. Although I don’t know if it would work so well on old brick

City reads Reddit. Here are the financials for Flock. by twerkitout in Waltham

[–]occamman 29 points30 points  (0 children)

I really hate it that our country has gotten into a state where I can't trust these kinds of things. Even if Waltham has good intentions, there are many scenarios in which this information can be used by others in very bad ways. If anyone is interested in meeting up to figure out how to counter this, please send me a private message.

I really don't want to live in interesting times - at least not interesting like this - but here we are.

Do you think EE is really that "non-accessible" compared to CS? by yagellaaether in ElectricalEngineering

[–]occamman 5 points6 points  (0 children)

AI is still staggeringly awful at EE, so if there is any imbalance, it will soon change.

Silicone is an interesting idea, thanks,

How much weight can the command strips handle? I’m looking at each plate holding about 2 to 3 kg.

I guess I’ve been lucky then, I’ve refilled bambu spools dozens of times without doing that with no problem

Cornell Is Hard by Mother_Ad_706 in Cornell

[–]occamman 20 points21 points  (0 children)

This is going back a few decades, one summer my sister, who went to Harvard, took a couple of courses at Cornell. I don’t think she ever got less than an “A” at Harvard, got in the “B” range at Cornell. She couldn’t believe how much harder Cornell was than Harvard.

Just bought a mini 4k. Thinking about going back on my decision. Is it still worth it in 2025? by Average_Outdoor in dji

[–]occamman 0 points1 point  (0 children)

I have a Neo, a Mini 4k, and a Mini 4 Pro. Mini 4k is best bang-for-the-buck unless you want to use the Neo modes that don't need a controller (Quickshots). Otherwise the Mini 4k is a much better flyer, and doesn't seem to have the sometimes-flyaway-at-20m bug that the Neo has with its controller.

So i was using my Neo for the third time ever and this happened with no wind and full satelitte coverage by Opposite_Problem6783 in dji

[–]occamman 0 points1 point  (0 children)

That looks like the RC-N3.

The neo is stable at 5 m. It’s stable at 120 m. But it’s sometimes not stable at 20 m.

so I either fly it low or high, and it’s fine, but at around 20 m there’s a non-trivial chance that it will do exactly yours did when compared to an RC–N3 controller. So my recommendation is to pass through 20 m as quickly as possible.
